ok im gonne get straight to the point
as the title says the CEL came on for it,got it checked at autozone, its listed as cam position sensor straight but the problem is i dont know which sensor that is (theres 2 sensors correct?) would i have to re-diagnose it and find out which sensor it is or is that just the name of it? I would rather replace it with a OEM but i dont want to take too long replacing it. thanks in advance guys. BTW, i can and will replace it myself
